Rabbit anti-Human RGS17 Polyclonal Antibody

Uniprot Id

Q9UGC6

Target Species

Human

Target Name

RGS17

Target Full Name

Regulator of G-protein signaling 17

Target Function

Regulates G protein-coupled receptor signaling cascades, including signaling via muscarinic acetylcholine receptor CHRM2 and dopamine receptor DRD2. Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form. Binds selectively to GNAZ and GNAI2 subunits, accelerates their GTPase activity and regulates their signaling activities. Negatively regulates mu-opioid receptor-mediated activation of the G-proteins.

Target Subcellular Location

Membrane. Cell junction, synapse, synaptosome. Nucleus. Cytoplasm.

Target Tissue Specificity

Predominantly expressed in the cerebellum. Also expressed in the cortex and medulla. Weakly expressed in a number of peripheral tissues notably spleen, lung and leukocytes.

Target Synonyms

hRGS17; Regulator of G protein signalling 17; Regulator of G protein signalling Z2; Regulator of G-protein signaling 17; RGS-17; RGS17; RGS17_HUMAN; RGSZ2

Target Background

This gene encodes a member of the regulator of G-protein signaling family. This protein contains a conserved, 120 amino acid motif called the RGS domain and a cysteine-rich region. The protein attenuates the signaling activity of G-proteins by binding to activated, GTP-bound G alpha subunits and acting as a GTPase activating protein (GAP), increasing the rate of conversion of the GTP to GDP. This hydrolysis allows the G alpha subunits to bind G beta/gamma subunit heterodimers, forming inactive G-protein heterotrimers, thereby terminating the signal.
